目前的研究显示，纳秒短脉冲光诱导化学反应可使燃烧尾气中的氮氢化物减少，因此研制实用化的短脉冲光源引起了人们新的兴趣．已有的短脉冲激光光源，因体积大或价格昂贵不适合应用要求．微波是一个高效清洁能源，商用磁控管的最短脉冲宽度为微秒量级，用其产生的放电等离子体 The current research shows that nanosecond short-pulse light-induced chemical reaction can reduce the nitrogen hydride in the combustion exhaust gas, so the development of a practical short pulse light source has aroused new interest. The existing short-pulse laser light source is not suitable for application due to its large volume or high price. Microwave is an efficient and clean energy, the shortest pulse width of commercial magnetron is on the order of microseconds, with its generated discharge plasma
